Oh I don't know, but isn't the problem really that the amiga is bit more complicated than those consoles etc? From what I remember when I had a real amiga, it really involved quite a lot of tweaking with settings (some games didn't work with more than one drive, some didn't work with more than 512 kb chipmem etc etc). So to me it seems like it is about how accurate and faithful you want the emu to be...?

And then I feel that WinUAE is so good there really isn't need for anything else... I wouldn't want to say that Fellow (or WF) is bad, but compared to WinUAE it's not very good.
